Understanding Blockchain

Definition and key features

Decentralisation: One of the fundamental characteristics of blockchain technology is decentralisation. Unlike traditional systems, which rely on a central authority to manage and control data, blockchains distribute the data across a network of computers (nodes), eliminating the need for intermediaries. This decentralisation reduces the risks associated with a single point of failure, ensures data integrity, and fosters a more democratic approach to data management.

Immutability: Immutability refers to the unchangeable nature of data stored on a blockchain. Once a transaction has been validated and added to the Blockchain as a block, altering or deleting the information becomes extremely difficult, if not impossible. This is due to the cryptographic hash functions that secure each block and the consensus mechanism that requires most of the network to approve any changes. Immutability ensures data integrity and provides an indisputable record of transactions.

Security: Blockchain technology offers robust security features, making it difficult for malicious actors to compromise the system. Each block contains a unique cryptographic hash that links it to the previous block, creating a chain of interdependent blocks. This, along with the distributed nature of the network, makes it nearly impossible for hackers to alter the data without being detected by other nodes. Additionally, most blockchains utilise consensus algorithms, such as Proof of Work or Proof of Stake, which require nodes to solve complex mathematical problems or hold a stake in the network, further deterring attacks.

Transparency: Transparency is another key feature of blockchain technology. Public blockchains, in particular, allow anyone to view and verify transactions, fostering trust among participants. In addition, although transaction details are visible, user identities are typically protected through cryptographic techniques, ensuring privacy. This combination of transparency and anonymity makes Blockchain attractive for various industries seeking secure, verifiable, and auditable records.

A brief history of Blockchain

The concept of blockchain technology was first introduced in 2008 by an anonymous individual or group known as Satoshi Nakamoto. In their groundbreaking whitepaper, Nakamoto proposed a decentralised, peer-to-peer electronic cash system called Bitcoin, which would utilise blockchain technology to record and verify transactions securely. The Bitcoin network officially launched in 2009, marking the beginning of the blockchain era.

Although Bitcoin demonstrated the potential of blockchain technology, its primary focus was on digital currency transactions. In 2013, a young programmer named Vitalik Buterin proposed a new blockchain platform called Ethereum, which aimed to expand the capabilities of Blockchain beyond cryptocurrencies. Ethereum introduced the concept of smart contracts, self-executing agreements with the terms directly written into code. Since then, numerous other blockchain platforms have emerged, each offering unique features and applications.

Types of blockchains

Public: Public blockchains, such as Bitcoin and Ethereum, are open to anyone who wishes to participate. They are entirely decentralised, and their consensus mechanisms ensure no single entity can control the network. As a result, public blockchains are transparent and secure, but they often face scalability issues due to the energy-intensive nature of their consensus algorithms.

Private: Private blockchains, on the other hand, are restricted to a specific group of participants, such as members of an organisation. While these blockchains maintain many of the same features as public blockchains, they offer greater control over who can access and validate transactions. As a result, private blockchains are often more scalable and efficient than their public counterparts, but they sacrifice some degree of decentralisation and transparency.

Consortium: Consortium blockchains, also known as federated or permission, are a hybrid of public and private blockchains. 

Financial Services

Cryptocurrencies

Bitcoin: The first and most well-known cryptocurrency, was created in 2009 as a decentralised, digital alternative to traditional fiat currencies. It allows users to send and receive payments directly without the need for intermediaries like banks.

Despite its volatility and regulatory challenges, Bitcoin has gained significant traction over the years, with many businesses and individuals adopting it as a payment and store of value.

Altcoins: Following the success of Bitcoin, numerous alternative cryptocurrencies, or altcoins, have emerged. These digital assets offer unique features like faster transaction speeds, enhanced privacy, or specialised use cases. Some popular altcoins include Ethereum, which supports smart contracts and decentralised applications; Litecoin, which focuses on faster and cheaper transactions; and Ripple (XRP), which aims to facilitate cross-border payments between financial institutions. As the cryptocurrency ecosystem continues to evolve, altcoins are gaining increased recognition and adoption, further demonstrating the potential of blockchain technology in the financial sector.

Cross-border transactions

Faster and cheaper remittances: Blockchain technology has the potential to revolutionise the way cross-border transactions are conducted.
